Perhaps this could be written as #else, since we have no further
alternatives (2.22.0 being our minimum).  Up to the maintainer if it is
worth changing.  Otherwise I think the end result is reasonable, and you
were able to avoid the leaks.

[Qemu-devel] [PATCHv5] tests: add qtest_add_data_func_full

[Marc-André Lureau]

Allows one to specify a destroy function for the test data.

Add a fallback using glib g_test_add_vtable() internal function, whose
signature changed over time. Tested with glib 2.22, 2.26 and 2.48, which
according to git log should be enough to cover all variations.
